Fig. XXXI is a detail sectional elevation-vimv of the loaf after it has been shifted laterally intov the secondary bottom and end folding' means,"

and after theend has been folded up at the bottom and down at the top. the position of the upper folding blade 1418 being indicated by dotted line. Fig. XXXII is a detail perspective of the end of a loaf showing the method of folding theA wrapping paper L13 thereon. Fig. XXXIII is a detail elevation view of the electric motor drive with a chain of gears, which is oftentimes the preferred upper frame part et on which the various* machine are disposed and arparts of the,

i rang'rcdv to cooperate with each other. An

end plate 5 is provided at the rear.

yThe machine is preferably driven by an electric motor G which may be provided with a. shaft 7. aworm Sand gear 9. The gear 9 is disposed upon the driven shaft 11 ofthe machine and these parts are lnclosed in a casing 10, as clearly appears in V. However,y for most purposes I have ascertained that the chain of gears illustrated in ,.fFig. XXXIII, on account of its simplicity and because of the ieXibility and slipping of the belt, will be preferred. rIhe worm and worm gear are most economical. The train of spur gears, while they are somewhat more cumbersome, are found to Work more satisfactorily under most conditions. The motor is disposed upon suitable brackets on the lower frame part 2. l Thesprocket wheel 12 1s disposed gon this driven' shaftll and is connected l,by sprocket chain 13 to the sprocketnvheel 14 on the shaft 15. See Figs. 80 III andVI.

-On the shaft 15 is an intermittent gear 16 which meshes with'a corresponding intermittent gear 17 that-drives thek shaft 19, so that the shaft 19 is intermittently driven from the said gear 15. Sprocket wheels 18 are disposed on the shaft v19 and around these are disposed and arranged sprocket chains 20. 20, constituting with the cross bars 21, 21, the endless carrier for feeding the loaves of bread into the machine. The

ends of the cross bars'21 project .into the 'guide ways 27, 27 at each side and are supported'by same. The lchain 20 at the front of the machine is disposed around the sprocket wheel 22 on shaft 23 andsis also arranged' around the sprocket wheel25 on the shaft 26 toward the rear. partk of the machine beneath the sprocket whe`el518. The guides 27 are supported by the bracesf2-1ex tending forwardly fromthe front part'of the frame ofthe machine, and'these two parts uniting form the support for the front-V sprockets 22 of the feeding carrier. A series of longitudinal slats 28 are disposed between guides 27 and supported by braces 24.

The intermittent gears 16 and 17 are adjustable in their relation to the loaf feed carrier.' A hand-nut 19^ isthreaded on to' the end of the shaft 19, see Figs. I, II, VI 110 and IX. A disk-19B is movable .longitudinally on said shaft 19 by means of avkey 19, and is providedvwith -an engaging pin 19D on its face. See Figs. VII and IX. The intermittent gear 17 is connected to a flange 115 17A by sleeve 17B, which embraces the shaft 19. The outer part of the sleeve constitutes a journal running in asuitable bearing on the frame 3. A series of holes 17C correspond to the pin 19Don the disk 19B. A re` 120 taining collar'17D is on the shaft I9 to'proplerly locate the gear 17 and its sleeve. From this description it will be seen that by loosening the hand nut 19A,the disk 19B` can he withdrawn so that the pin 19D will disen- 125 gage the flange 17A, and the pin can be ad- `jus-ted in any one of the series of holes 17C. In doing` this, of course, the relation of the shaft 19 to the intermittent gear 17 will be varied, so that the relative position of the 139 just described clearly [appears in Figs. VI'- to X, inclusive.

Yielding guide arms 29, 29 for centering the loaf into the machine are supported lupon vertical shafts 30, 30, secured to the 'frame at each 'side and are joined together by link`32 connected at pivot 31 on a rearwardly-projecting arm 31 and by pivot 31 on a forwardly-projecting arm 31 on the op.- posite side of the machine., Tension is put upon these 'parts by the spring 33 connected to the link 32. These parts clearly appear in Fig. XI.` The loaf, when advanced by the carrier, will be engaged by the guide 29, 29 at each side and will be brought to the central line of travel. j' p IfVhen' the loaf is delivered by the intermittent movement into thema-chine in position to'be wrapped, it will be disposed directly'above the elevator' platform 34 which l, is carried upon'the upper ends of a pair of rods 35. These rods are disposed in suitable vertical 'guides 36. The elevator is raised `upwardly, ycarrying the loaf upwardly by' f means of the' lever 38 which is fulcrumed at 39 and is connected by the link 37 to the pivotf37 just beneath the elevator' platform. The-short arm 40 of the lever carries the roller 41 which is acted upon by cam 42 which is disposed inproper timed relation upon the shaft 11. It will thus be seen that as the shaft 11 rotates itv will elevate the loaf of bread upwardly into the folding device.y

The first step of they folding process 1s 'clearly indicated in Fig. XXVI, where the ,roll 44 on a suitable shaft 45 at the rear of the machine, andis dropped downwardly` :finto a loop around the idle roll 48, which isv also a weight for regulating the tension, thence upwardly between the feed rolls 50,

'i 52. The weighted roll 48 revolves on its axle 48', which is carried in suitable guides 49 that are disposed. on `vertical suspended guide rods 47.` 47, see particularly Figs. I.

III and IV. The roller and guide rods Vare carried bythe rearwardly projectingr bracket 46, secured to the end plate 5 ofthe machine. The feed roll 50 is carried upon the shaft 51 and coperates with the upper feed roll which is carried on the shaft as clearly appears in lFigyIV. The paper is delivered forwardly through suitable guides 54 into the machine, the same being carried forward by a pair of endless belts 55 carried on the p roller`56 on shaft y57 at one end and thepai'r -of adjustable rolls 58 which are supported the adjustable journal pins 59 on the other end. The vfront pins 59 are supported by the adjustable arms 60 which are carried on the underside of the adjustable folder table sections 146 by set screws 61.

A pulley 62, see Figs. III and VI, on the shaftll is connected by a round belt 63 to pulley 64 on the shaft 65. Shaft 65 is supported on the brackets 46 toward the rear of the machine. See Fig. III. This shaft 65 carries the pulley 66, which is connected by the belt 67 to drive the pulley 68, see' Figs. I, XIII and XIV, on shaft 57. The roll 56 is on this shaft and is thek rear part of the paper carrier.

An adjustable stop means is provided for klocating the wrapping paper in the required line 15-15 of Fig. I. The Stop is carried on the sleeve 55B which is adjustable upon the rod 55C byvmeans of the finger 55', which is adapted to engage notches 55A. .t An inwardlyprojecting arm 55D is connected by .a -fiexible sheet of metal 55E to the crossbar 55F, which carries 'downwardly-projecting stop pins 55G projecting downwardly through the slots 55H. The paper passes above Ithe guide plate 4^, which is secured and supported in place by the cross bar 4B and passes beneath the plate 4C which is supported and retained in position by the cross bar 4D, see particularly Figs. XV, XVI and XVII.

A plate 69 is disposed below the web of wrapping paperl 43. A transverse knife 70 is above the same, being urged downwardly by the spring 76. The rock shaft 74 carrying'arm 75 is connected to elevate the knife, as appears in Fig. I. These parts and the associated knife are held upwardly by trigger ngers 75, see Fig. I, which are actuated by suitable means, in suitably timed relation to each other, so that the knife vsnaps down and severs the 'paper at predetermined periods. These parts in detail are made the subject matter of an independent patent application, and therefore are not described morel fully at this point. The sprocket wheel 79 on shaft 78 is driven by lthe sprocket chain 8O from the sprocket wheel these parts inoperation, is disposed on the shaft 51 and is controlled by the lever 83 which is connected by the connecting rod 84 livery f paper from. the roll. This same cam also performs the further duty of` throwing the folderA and knotter mechanism into gear by controlling a suitable automatic clutch therefor. This clutch is so constructed that if a'loaf is not delivered it will automatically bethrown out until a loaf is delivered into the machine, when the machine will be Set in operation and will act both the waste 0f paper and of twine and n prevents any loss 0r inconvenience from the failure of an operative to place a loaf 0n the -loaf feeding carrier. A reference to Fig. XII shows that the4 cam 77 `acts upon a roller 128 carried upon the arm or lever 127,

which is pivoted or fulcrumed at 127. A link 125, connected at 126. to the lever 127, connects to lever 130, see Fig. XIX. The link or connecting-rod 125 is pivoted to the lever 130 at 129. -The lever 130 isfulc'rumed at 1,31, and is held yieldingly in position by the tension spring 130, see Fig. XIX. The,

details v0f this clutch appear in Figs. XIX to XXIII, inclusive. The relation of the parts to the knotter andV folder cam appear v from Fig. I. The sai-d cam is-driven by the sprocket wheel 124, see Fig. XXIII, by the sprocket chain 123 which extends upwardly7 see Fig. I, and drives sprocket wheel 122 which is on the shaft 121', see Figs. I and II. f

The sprocket wheel 124 is carried by the clutch member 138 to whichl it is keyed, the same being supported revolubly upon the shaft 11. The clutch member 141 is keyed to the shaft 11, see Figs. XXI and XXII. The clutch member 138 carries the pivoted jaw 142, which is pivoted at 144 and is held yieldingly inward by the blade spring 145 which is fulcrumed .at 138', engaging a suitable notch 138A in the clutch mem- Y ber at one end, and a vsuitable notch 142 on the dog v142 at the other end, asl

-' and is held yieldingly againstthe bracket bythe coiled spring 136 on'said vpin 136. A spring 137 connects the arm 134 to the frame 3 and urges thevsame laterally toward 1 the engaging position, see Fig. XX. The free end of the arm 134 is beveled on its under sideat134, bringing it to a point where it rests upon the periphery of the clutch member 138.' When the arm 130 rocks upon its pivot, the lower end thereof en ages the end of the bell crank 132, which 1s pivoted at 133 on the bracket 135 and rocks the bell crank on its pivot so as to move the arm 134 upon the loaf as it progresses. This avoids shifter. l

ways 91, 91, supported on the top of the mato one side, to allow the jaw 142 to engage the clutch member 141;. j

A plate 139 is secured to the clutch member 138 and embraces and retains the clutch member 141in its coperative" relation-.with the pivoted jaw 142, and the arm y134 to be actuated indirectly by the loaf which trips and starts the cycle of the machine, so that if no loaf is delivered by the Vintermittent movement of the loaf feeding means, no paper is fed, the folders do not operate and the tying devices are not set in motion.

`The side folders 86, 86 oftheloaf are dis posed and carried on the downwardly-projecting arms at 87, 87, from'the loaf shifter, being pivoted at 87', 87 at the'lower ends of said arms. These downwardly depending arms 87, 87 are each carried by across bar 88, 88 of the laterally-shifting carrier frame of the loafshifter. These are adjustable to and from each other by the right andleft hand screw 96, which is journaled at 90, 90 in the end bars 90, 90 of said carrier or These arev carried on parallel rod chine in suitable clip .supports 92, 92 on the cross bars 93. .These parts are carried by the upright posts 94, 94 at each Vcorner of the machine. The rods 91, 91 extend from zthe front end to the rearend of the machine,

as clearly appears in Figs. IV and XXIV. Adjustable cross bars 88 are carried :upon the longitudinalsupporting rod ways 89,' 89 and are adjustable .by manipulation of the hand wheel 96 by which the right and left lhand kscrew 96 is controlled and the position of said cross arms 88 is determined. The tops of 'the posts 94 are joined together by the longitudinal vbars 95, which retain` these parts rigidly in position. v

The primary bottom folder 98 iscarried on a suitable frame at the rear lof the machine, and is adapted to reciprocate underneath theelevated loaf and fold the downwardly-depending portion of wrappeiij43 underneathl the same, as clearly appears in Figs.v XXVI and XXVII. The downg wardly extending portion' appears in VXXVI. This folder is carried by a suitable reciprocating plate 101V on "suitable ways.

,Supported on this plate 101 are the primary end folders 97, carrying the pivoted parts 97 97, see particularly Fig.v XXVII.-

Rearwardly-projecting arms 97 A extend from the said 'folder and are carried by a suitable transverse guide rod 100 which is supported in a suitable central bracket on the plate 101. These parts are adjusted to and from each other by the right and left hand screw 99,y

see particularly Fig. II. The movements of these parts are controlled by the lever 109, which is pivoted at 110 on therearwardly extending arm 110. The lever is connected to link lll'bypivot 112 and the forward 'end of the link isconnected by `pivot 113 to the reciprocating plate :101.` 'A .rod 103 is connected .at .pivot 108 to .the lever 109, see Figs. l{[I and III, and is. actuated by the cam r107 on theshaft 11. The rod is supported rod ways ,102,. 102,. see: particularly Fig.

The details of the needle 163 and itsactuating means 164 clearly appear in lilig.- III. These .partsnare not'f-ully detailed here as they .arewrnamle` the-Subj ect .of .a special patent application;

The laterallyshiftng carriage 152. is supported .on'a pair of rod-Ways .156 and 157,

' :the loafiisshifted endwise into-vthe knotter and 'when'.the .same -is timed, vit .is .dis-

The -loaf is .ejectedfonto platform 173 betweenthe side guards 174.

The carriage 152 is provided ywith .adjustable.jguides153l;53 at `each end, the 'ends 155, 155 being [adjustable to :and from each other by Ya suitable screw means. p

The sprocket :79--on shaft '78 is driven by thesprocket 8O and is coupled with the sha ft 78 so as to drive the same When the rod 84 andthe lever 83 'are actuated by the loaf which is vbeing carried intoA the machine. W'hen the loaf engages the trip arm 85, itcoupl-es the sprocket 79 with the shaft` 78 so as to drive the paper cutting mechanism and .the same movement of the arm 83 throws in the clutch 82 so as to drive the l' shaft 51to actuate the paper feed rolls. At

the other end of shaft 78 is the cam 77 for actuating the paper knife which also actuates the rod 175 for controlling the clutch mechanism through which the cam roll 121 is driven. lYhen a loaf of bread is started into the machine and engages the trip arm S5. the clutch mechanisms are actuated to throw into gear the papercutting mechanism, the paper feeding mechanism and the cam roll for actuating various parts of the machine such as the loaf shifting mechanism, the mechanism forshifting the knotter table and for actuating the knotting needle. -These connections form no part of my invention as they are shown in my co-pending applica-y tion Serial No. 801,268, filed Nov. 15, 1913. The parts are so timed that when the folding operations are completed, `the knetter table 152 is in position so that the loafisshifted from the table 1-16 to the knotter table 152 and the movement of the knotter tablecarries the loaf from between the folders 8G to Vcomplete the knotting operation.

The details of .this structure can be greatly varied without departing from my invention. I have, however, embodied the same in a very satisfactory and effective form, and I desire to claim the structure` specifically, so far as possible, and also to claim the invention broadly as clearly appears from the appended claims. l
